YOUN Beauty Vitamin C Face Serum 20% (60 ml) — Sodium Ascorbyl Phosphate with Hyaluronic & Ferulic Acid for Brightening and Hydrat

Formulated by Dr. Anthony Youn, this 60 ml antioxidant serum combines a high-strength, bioavailable form of vitamin C with complementary actives — ferulic acid, vitamin E, and hyaluronic acid — to support skin radiance and moisture balance. The recipe emphasizes stability and clean ingredients: sodium ascorbyl phosphate offers a more oxidation-resistant vitamin C source, and the product is housed in an opaque white glass bottle to limit light exposure. Additional botanicals and emollients like jojoba oil, aloe vera, witch hazel, arginine, and centella asiatica help soothe, hydrate, and support the skin barrier.

How does this serum improve skin brightness without irritating sensitive skin?

Instead of using ascorbic acid, this serum relies on sodium ascorbyl phosphate, a gentler, water-soluble derivative of vitamin C that provides antioxidant benefits with lower irritation risk. The formula balances potency with calming and hydrating ingredients to reduce the chance of redness or dryness for many users.

• 20% sodium ascorbyl phosphate for stable vitamin C activity
• Centella asiatica and aloe vera to soothe inflammation
• Jojoba oil and hyaluronic acid to replenish moisture
• Fragrance-free, paraben-free, and vegan-friendly formulation

What role do ferulic acid and vitamin E play in this serum?

Ferulic acid and vitamin E act as complementary antioxidants that enhance and stabilize the vitamin C system, helping to neutralize environmental stressors that can dull skin. Together they support the overall antioxidant capacity of the serum, improving efficacy without increasing active concentrations.

• Ferulic acid boosts antioxidant synergy
• Vitamin E helps protect lipids and enhances vitamin C stability
• Combined ingredients aim to defend skin against daily oxidative stress

How should I incorporate this serum into my daily routine?

Apply the serum once or twice daily after cleansing and before thicker moisturizers or sunscreen. Start with a small amount to assess tolerance, then increase use as your skin adapts; always follow with broad-spectrum SPF during daytime use.

• Use 1–2 drops for the face and neck; gently pat until absorbed
• Layer under moisturizer and SPF for daytime protection
• Store in its opaque white glass bottle away from direct light

Is the packaging designed to preserve potency?

Yes — the serum is presented in an opaque white glass bottle to minimize light exposure and maintain ingredient integrity over time. The bottle choice helps slow oxidation, so each drop retains activity longer than if stored in clear packaging.

• Opaque white glass reduces light-induced breakdown
• 60 ml size balances supply with typical usage rates
• Formulated and made in the USA with clean-label commitments
